Product Description

This is a highly cross-adsorbed donkey anti-rat IgG (H+L) secondary antibody labeled with our bright and photostable CF® dyes. To minimize cross-reactivity, the antibody has been adsorbed against bovine, chicken, goat, guinea pig, Syrian hamster, horse, human, mouse, rabbit, and sheep serum.

  • Highly cross-adsorbed for specific staining with minimal background
  • Available in 12 bright and photostable CF® dyes
  • Suitable for western, immunofluorescence, and immunohistology in FFPE tissues

Note: Conjugates of blue fluorescent dyes like CF®350 are not recommended for detecting low abundance targets, because blue dyes have lower fluorescence and can give higher non-specific background than other dye colors.
